I think you might not be seeing the holders at ground level that the pvc is in.

When I had my small greenhouse up (lived down the road from you in Sagamore Hills) I used metal brackets, home depot, to hold my pole.

Then used a gosh right off the top of my head I can't remember the gage of the plastic, as I would start tomatoes in January and then move to the greenhouse in March.
